Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to compare operative time, patient reported outcomes, surgical complications, and surgical outcomes between the tunneling versus dissection technique during robotic assisted sacrocolpopexy (RA SCP).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Women with symptomatic, stage II to IV POP who plan RA SCP at UTMB Health will be approached to participate. Using the study protocol inclusion and exclusion criteria, patient's eligibility will be determined. All eligible subjects will provide the written informed consent before any research data is collected. All screening assessments will be completed at a preoperative, in-person, clinic visit, and within 60 days of surgery. The subject will then undergo randomization to tunneling versus dissection technique during RA SCP with the total sample size of 40 female subjects (20 per group). Concomitant procedures for POP or urinary incontinence are permitted and will be based upon the operating surgeons' standard clinical practice and best clinical judgement. Subsequently, the subject will have postoperative follow up at 2 weeks, 6 weeks and 3 months

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dissection Technique

The peritoneum is incised superficially and opened longitudinally from the sacral promontory, downward to the posterior cul-de-sac and the posterior vaginal wall to create retroperitoneal space for the SCP mesh.

Group Type PLACEBO_COMPARATOR

Dissection Technique during RA SCP

Intervention Type PROCEDURE

As described in the intervention arm above

Tunneling Technique

A retroperitoneal tunnel is created by undermining the peritoneum with the robotic scissors and/or needle driver which is placed in the peritoneal opening over the sacral promontory. The tunnel is created just medial to the right uterosacral ligament and toward the posterior vaginal wall by using forward pressure and a sweeping motion to create a space within the retroperitoneum
